Short description of error
Custom Navigation is not working in Sculpt Mode
Exact steps for others to reproduce the error
I use custom navigation in viewport (Numpad 1 + Left Mouse for Zoom and Numpad 2 + Left Mouse for Pan), emulate Numpad option is enabled in preferences. This navigation work fine in Object and Edit Mode, but if I change mode to Sculpt - navigation not working. I don't know why, but there is a conflict with a command "sculpt.brush_stroke" which is assigned to Left Mouse in hotkey editor (Sculpt (Global)), if I uncheck this command navigation start working but I can't sculpt, sculpt stroke not working. This problem also with Texture Paint, Vertex Paint, Weight Paint modes. Below is video of this problem. I also tried to assing another hotkey for navigation - it's also not working, it's working only with default Blender navigation.
